DANIEL JOSEPH, OF NEW YORK, N. Y.

HAT-FRAME MACHINE.

amet.

To aZZ whom it may concern:

Be it known that I, DANIEL Josnrrr, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Hat-Frame Machines, of which the following is a specification.

This invention relates to hat frame forming machines particularly adapted for use in the manufacture of twisted wire frames for ladies hats.

The general object of the invention is to facilitate the operation and reduce the cost of constructing twisted wire frames for ladies hats and to preserve the pattern of any hat frame constructed.

To these ends the invention consists of a machine comprising a spindle on the upper end of which is mounted an adjustable head carrying a plurality of adjustable form fingers and around which a wire'is wound for forming the various shapes of hat frames used by ladies.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming a part thereof in which Figure 1 is a longitudinal sectional view of my improved machine and showing in dotted lines a hat frame formed thereon. 2 is a top plan view of the machine. Fig. 3 is an enlarged plan view partly in section of one of the removable frames for holding the adjustable form fingers. Fig. 4 is a perspective view of one of the adjustable arms for supporting the form finger frames. Fig. 5 is an enlarged detail view of a portion of one of the gage rods. Fig. 6 is a perspective view of the upper portion of one of the form fingers. Fig. 7 is a top plan view of a hat frame formed on my machine.

The machine comprises a base A, a spin dle B on the upper portion of which is mounted an adjustable head 0, a plurality of radially extending arms D, and a plurality of adjustable form fingers E around which is adapted to be formed a wire hat frame F. The base A is adapted to be secured to a suitable support 1 by means of the screws 2 and has formed in its upwardly extending socket portion 3 a ball bearing race at.

Specification of Letters Patent.

Application filed February 28, 1913.

Patented Aug. 11, 1914. Serial No. 751,355.

Revolubly mounted within the socket 3 and supported by means of the ball bearing connection 5 is the vertical spindle 6 which is bored at its upper end as at 7 to receive a gage rod 8 for gaging the height of the crown of the hat. The gage rod is adjustably held within the bore 7 by means of the set screw 10 and has its upper end notched as at 11 to receive the top wires of the crown when the hat frame is being formed.

Adjustably connected to the spindle by means of the set screw 12, is the head piece C which is preferably of the shape shown in the drawings and provided with a series of sockets 14 angularly arranged within the head piece and adapted to receive the radially extending arms D, which arms are preferably of rectangular shape in cross section so as to prevent their turning in the sockets, and have their inner or angular bearing portions 16 adjustably held within the sockets 14c. To the outer or horizontal portions of the arms are removably held, by means of the set screws 17, the elongated frames D in which are pivotally held by means of the pivot pin 19, a plurality of elongated bearing plates 20. These bearing plates are secured in spaced relation to each other and are provided at one end thereof with the slotted openings 21, in which are mounted the adjustable form fingers E, the adjustment of which is permitted by means of the thumb screws 23 mounted in the sides of the frames, and engaging the side of one of the bearing plates as clearly shown in Figs. 2 and 3. l

The form fingers may be adjusted to any desired angle and are provided at their upper outer edges with notches 24: for receiving the wires for forming the hat frame when the machine is in use. The upper inner edges of the form fingers, are provided with the bulged or extended portions 25 which prevent them from falling through the openings in the bearing plates when the pressure on the plates exerted by the thumb screw 23, is released. All of the frames carrying the adjustable form fingers may be readily removed from the radially extending arms when it is desired to preserve the shape of a particularstyle of hat frame.

Loosely mounted on the spindle and located beneath the adjustable head G is a movable collar 26 which is connected by means of a plurality of connecting rods 27, pivotally connected at their lower ends to the movable collar 26 and pivotally connected at their upper ends to the radially extending arms 15.

A gage rod 29 mounted in the adjustable head 0 and held in any adjusted position by means of the lock nut 30, and a gage rod 31 mounted in the base of the machine A and held in any adjusted position by means of the lock nut 32, are provided for limiting the upward and downward movement of the collar when the machine has been set for the formation of a special size of hat frame. The machine as shown on the drawing, in adjusted to permit of the manufacture of the small size of hat frame but to permit of the manufacture of the larger size of hat frames, the frames D oppositely disposed from each other and provided with the gripping knobs d are first withdrawn from the head C to the proper required distance, a gage D being formed on one side of one of the radial extending arms D and registering with the beveled side of the head C for gaging the distance required, as clearly shown in Fig. 1. The withdrawal of frames D, and arms D through the connecting rods 27 and collar connection 26, cause ll of the other radially extending arms D to move outward in a uniform manner. After the arms have been adjusted to their proper position the lower end of an o erating rod 34 (see Fig. 1) is then inserted into an opening 35 formed in the angular portion 16 of one of the radially extending arms, thereby permitting by its engagement with the outer surface of the beveled portion of the head, to secure the form fingers in their outer position, until the complete formation of a hat frame, when the operating rod is removed to permit the inward movement of the form fingers so that the completed hat frame may be conveniently removed without bending. The inward movement of the form fingers is limited by means of the collar 26 engaging the upper end of the gage rod 31 which has been previously set and locked by means of the lock nut 32.

A spring clip 40 mounted on the top side of the head C is provided for conveniently holding the operating rod 34: when not in use.

In the operation of the machine and after the form fingers have been properly adjusted to permit of the desired shape of hat frame to be formed and after the operating rod 34 has been set within its proper opening 35 in one of the radially extending arms to give the hat frame its desired size, the wire usually used in the construction of hat frames is first wound around the form fingers, thereby forming what are technically called the round and round wires and which give the substantial circular shape to the coronet or crown. As the round and round wires are being applied, the operator takes a piece of wire of the proper length, lays it across the top of the crown and bends it down, twisting it around the top round and round wire. This operation is repeated until a sufficient number of what are technically called the fore and aft wires have been set in place, they crossing each other at the center of the crown and being supported by means of the central gage rod 8, the last wire being twisted around the others at the crossing point. After this operation the free end of each wire is twisted around the next round and round wire, and then the next fore and aft wire is secured in like manner until the final attachment of all such wires is effected with the lowest round and round wire of the brim or coronet according to the character of the hat frame to be made.

It is obvious that those skilled in the art may vary the details of construction and arrangements of parts without departing from the spirit of my invention and therefore I do not wish to be limited to such features except as may be required by the claims.

What is claimed as new is:

1. In a machine for forming wire hat frames, a frame, plates pivoted in the frame, and provided at their sides with openings, fingers adjustably mpunted in said openings and means carried by the frame for locking the plates and fingers in adjusted positions with relation to each other.

2. In a machine for forming wire hat frames, a frame, plates pivoted in the frame and provided at their sides and beyond their pivots with openings, fingers adjustably mounted in said openings, and having surfaces lying in the same planes as those in which the side surfaces of the plates lie, and a set screw passing through the side of the frame and engageable with one of the terminal plates of the series of plates.

3. In a machine for forming wire hat frames, a spindle, a head piece mounted upon the spindle and having sockets inclined down from the edge thereof toward the center thereof, arms fitting in the sockets and supporting adjustable fingers, said arms having openings, a detachable rod adapted to be inserted in the openings of the arms, a collar slidably mounted upon th spindle, and rods pivoted to the collar and the arms.

In testimony whereof I afiix my signature in presence of two witnesses.
